Unlock! is a series of cooperative card-based escape adventures from Space Cowboys. Each Unlock! game consists of sixty cards depicting objects, maps, and puzzles that can be activated, solved, or combined in an effort to access other cards and areas. Up to six players work cooperatively to solve each of the riddles and get through the deck within sixty minutes. The free companion app tracks the time allotted to win the game, while also offering hints and unlocking new, and necessary, elements. When the players believe they have figured out the code to escape each adventure, they will input the number into the app and escape the danger, or lose even more time in finding the real sequence.
